*Per Rev G requirements, any structure greater than 10', requires a climber safety device.
Self-Supporting Towers are limited in Height due to the nature of Antenna and Ice loads versus the Cantilever Nature Of Wind against them, offset by the weight of the Foundation and the cohesiveness of the soil to prevent the chance of tower tip over, as well as the strength of the tower members to withstand these Forces against them.
ROHN Tower Kits are designed based on assumptions made regarding Wind Speed, EPA (Antenna Load), Height, Standard Soil Conditions, Surrounding Environment and Duty. The Pre-packaged Kits contain the parts called for based on this Stock Design. The Stock Design of these Kits does not account for the Variations of Historic Windspeed, Number of Antenna(e) Loading at Specific Height(s), Soil Engineering recommendations, Adjacent Structures, Communications Purpose, or Geo-Political Rules, Laws and Codes That will be Applicable to Your Project. It is Recommended that you take the time to engage an local Engineer that has the expertise and available Information necessary to evaluate the Stock design for Applicability, fill out this form and send it to email@example.com
The ROHN RSL is a light weight self-supporting tower designed for use in broadband, public safety and security applications. The RSL reaches above line-of-site obstacles such as tree tops, hilly terrain and buildings. The RSL is shipped knocked down to reduce shipping cost and time.
STRUCTURE CLASSIFICATION = I
That due to height, use or location poses a low hazard to human life and damage to property in the event of failure and/or used for services that are optional and/or where a delay in returning the services would be acceptable.
EXPOSURE CATEGORY = C
Open terrain with scattered obstructions having heights generally less than 30 ft (9.1 m) This category includes flat, open country, grasslands and shorelines in hurricane prone regions.
TOPOGRAPHICAL CATEGORY = 1
No abrupt changes in general topography, e.g. flat or rolling terrain, no wind speed-up consideration shall be required.
3-SECOND GUST WIND SPEED WITH ICE = 40 MPH
DESIGN ICE THICKNESS = 1.0"
EARTHQUAKE SPECTRAL RESPONSE ACCELERATION, Ss = 2.50
The tabulated allowable effective projected areas (EPA) are limited to a maximum recommended value of 80 (ft2). EPA values shown as " - " indicate tower kit is not applicable for the corresponding wind speed. Site-specific designs are available upon request.
